Well, the big news is, there isn't any big news. The coronal hole
solar wind gust that was supposed to hit yesterday would appear to be
pretty much of a no-show, at least so far. The solar wind speed has
stayed elevated for several days, and it is still elevated now. It
never did, however, show any sort of a spike at the time when the high
speed solar wind was supposed to arrive here, and there hasn't been
any geomagnetic activity that I know of. So, on to bigger and better
things. There is yet another coronal hole that has rotated into an
Earth-pointing position as of today. We *should* be seeing some high
speed solar wind from it around the 7th. There are several small
sunspot regions visible on the solar disk tonight. Of the group,
region 208 looks to be the only one that has a chance of generating an
M-class flare, although it has been quiet so far.

Conditions for the last 24 hours :
No space weather storms were observed for the past 24 hours.

Forecast for the next 24 hours :
Space weather for the next 24 hours is expected to be minor. Radio
blackouts reaching the R1 level are expected.

Solar activity forecast :
Solar activity is expected to be predominantly low, with a chance for
isolated moderate flare activity during the next three days. Region
208 is a possible source of low level M-class flare activity.

Geomagnetic activity forecast :
The geomagnetic field is expected to be mainly quiet to unsettled for
the forecast period. Greater than 2 MeV electron flux at
geosynchronous orbit may persist at high levels for the next one to
two days.

Recent significant solar flare activity :
None
